This video demonstrates that Abbreviation Completion supports non-predefined abbreviated input. 7 different abbreviations for "SwingUtilities.invokeLater(new Runnable())" are all expanded into the same original code line.

For efficient demonstration, a shortcut key (Ctrl+Enter) is used to expand any text in the current line into the most likely abbreviation completion candidate. Note that older versions of Abbreviation Completion may not support the shortcut key.
